ODP Leg 167, Hole 1014A - Well Logging Data

Logging data are measurements of physical properties of the formation surrounding a borehole, acquired in situ after completion of coring (wireline logging) or during drilling (Logging-While-Drilling, LWD). The range of data (resistivity, gamma radiation, velocity, density, borehole images,…) in any hole depends on the scientific objectives and operational constraints.测井数据是对井眼周围地层物理性质的原位测量结果，其采集时机包括两类：一是取心作业完成后开展的电缆测井（wireline logging），二是钻进过程中进行的随钻测井（Logging-While-Drilling, LWD）。单井数据的覆盖范围（涵盖电阻率、伽马辐射、速度、密度、井眼成像等），取决于具体的科学目标与作业约束条件。
